SATUBATOR.

To all whom t may concern Be it known that I HARRY A. CUMFER, a

citizen of the United states, residin at chicago, in the county of Cook and tate of Illinois, have invented certain new and use' ful Improvements in Saturators, of which the following is a specification.

The'invention relatesto saturators. y

One of the objects ofthe invention is to improve saturators, whereby a moving sheet of absorbent materialis subjected to a saturant.

Another object is to provide a saturator for a continuously moving sheet, formed into l5 a plurality of loops depending into a tank containing a hot saturant, and means for' separately driving each loo Another object is toprovi e a saturator in which the length of the loops may independently be adjusted. Y Another object is to vprovide a saturator in which the loop-extending roll, normally near the bottomof the tank, may be raised above the tank for ease of threading the sheet thru the saturator. l l

Another object is to'improve the details of construction of machines of this character.-

Other objects and advantages will readily appear.' l

In the drawings v Fig. lis a longitudinal view of an embodiment of the saturator showing parts 1n elevation and parts in section.

Fig. 2 shows parts in end elevation and other parts in transverse section.

Fig. 3 is an enlarged section takenon lme 3 3 of Fig. e.

Fig. 4 is a. section taken online Llr-l ofy Fi 3. l Fig. 5 is a detail of means for 'raising and lowering either side of the loop so that the sheet will run true. v

Fig. -6\is. an enlarged view, showing parts in section of one of t e loop adj ustin means.. e Fig. 7 is a section "taken on line -7 of In all the views the'same reference chareters are employed to indicate similar parts. In making asphaltic' roofing material a vcontinuously moving sheetof an absorbent nature, such for example as a sheet of felt, or other similar fibrous fabric'or material to constitute the base ofthe finished roduct, is saturated with a hot water-proc g material, usually of an asphaltic nature. Owing to the relatively rapid movement of the sheet `thru a series of other cooperating machines, necessary for its economic production into a roofing sheet, a considerable length of the sheet must remain in the saturant a suilicient time to become thoroughly impreg nated. To make a tank egual in length to the length of that part o the sheet treated would be commercially impractical because of the improvident waste of space 65 and the high cost of rent such an expedient would entail. Therefore, in the present machine, I form the sheet into a serles of vertical loops and cause each loop to depend into a tank from a transversely disposed driven 7.0 roll located near the top of the tank. Such an expedient, however, would be substantially impractical if provision were not made or conveniently threading the sheet thru tie machine when the sheet becomes accidentally broken or otherwise discontinuous. To render this operation convenient I provide means for raising the loop-extending .rolls to points above, or near the corres nding bodily stationary loop-driving ro ls', so '80 that the sheet will then occupy a. substantially horizontal plane at the time and after it is introduced into the machine, and before being again formed into loops by lowering the loop-forming rolls.

A further refinement consists of means for adjusting the ends of each loop forming roll in order that the sheet may run true thruy the saturator.

In the drawings 5 represents the tank con- 90 taining the saturant, preferably located vbe-vv low the ioor line 6. rame members 7 and 8v extend along the sides of the tank, paral= lel with its sides, and slightl above the upper 'edge 9 of the tank. y itably --spaced apart along the frame members 7and 8 lare a plurality of pairs of roll journal bearin ,f 10 to 14, inclusive, .and'sup'poi-ted in sard bearings are. rol 1s 15 to 19, mclusiye. of these rollsis driven by a-mitergeer 20 mesh with a similar miter gear 21. 'lLhe miter gears 2O are secured to the driving shaft 22, which is support/ed in a series or journal bearings 23 near each of the driving miter gears 20. fihe rolls 10 to 18, inclusive, are driven in the saine direction, clockwise as the appear to the observer in Fig. 1, but the ro l 19 is driven in an opposite ydirection for a purpose to be hereinafter more fully 1 explained.

'lwo relatively adjustable receiving rolls 24 and 25 are properly supported near the lifront end of the machine to receive the sheet 26. These rolls are yieldingly held together by mechanism adapted oi' the" purpose of applying more or less tension to the sheet.

Near the bottom of the tank, as shown in Fig. 1, are a series of loop-extending rolls 27 to 31, inclusive. These rolls are supported at each end upon a rack structure comprising two racks 128 and these racks are held together by spacing rods 129 and 130. 'llhe sheet 26 passes below each ot the loop-extending rolls, as more clearly shown in Fig.. 1, and over the top of the respective bodily stationary rotatable driven rolls to 18, respectively, and by this means each of the loops of the sheet is driven by the respectivelydriven-rolls 15 to 18. The loop Hight 26', at the discharge end of Athe taiilr 5 is passed over the top ot the roll 19 and then towards the front over 'the roll 32.. 'lhe roll 32 is a pinch roll with respect to the roll 19, and these two rolls are adjustably placed near together. The roll 32 is driven by the roll 19, and the roll 19 is driven by the bevel gears and .21.` 'lhese rolls serve as supplementary ymeans for pulling the sheet through the machine..

ifi hand wheel 33 is secured to the end ci the rotatable shaft 34 and by means ot the bevel gears 35 'and 35', the bearings conn taining the roll 32 are raised and lowered at both of its ends so as to increase and decrease the pressure exerted upon the sheet 26 that passes between the rolls 19 vand 32, thereby to increase the :trictioiial resistance between the rolls and the sheet to inalie the driving etlect more positive.

Located on each side of the tank 5 and extending into the ground near the hot-toni of the tenir, as 'at 56., are a series et pipes 36, there beiiiga pair located mid-way between each pair oil driving rolls, or one pair oi pipes 36 `lor each loop. Secured to the pipes 36, and to each pair thereof., is a bracket 37, one for eachpipe, as more clearly shown in Fig. 3. The bracket is held in place by the bolt 38 'which causes the ring portion 39 or the bracket to intimately einbrace the pipe 36. 'lflhere is another pair oi spaced-apai'tbraclrets 40 near the upper end ci the pipes 36. These brackets are similar structure to that shown in Figu3, and are held on trie pipes 36 saine inannera vthe hand wheel48, then the sheet incense 'lhe raclr structure 128 passes freely thru the extended ends 41 of the brackets 37 and 40. rlihe rack structure 128 consists oit a cast rack' 42 having teeth 43 on one ol its sides. llt is preferably rectangular in cross section and is contained in a tube 44 which is split, as at 45, to permit entrance ofthe spur gear wheel 46 to engage the rack.

A. shaft 47 extends thru bearings 48 which project troni the bracket 37 and the gear wheels 46 are iixed to this shalt A. hand wheel 48 is the means for turning the shalt 47 in order to raise the raclr structure lcarrying the respective loop extending roll from the bottoni of the tank to a point near the upper portion thereof, for the purpose heretofore described.

'liheobject of placing the tube 44 over the rack 42 is to strengthen the raclt and to provide a uniformly even surface for passing thru the guiding brackets 37 and 40 without the necessity oit tooling the entire length of the rack.

Near the top of each ont the pipes 36 is a bracket 49 carrying a shieve 50 on its upturned end. 'lo each of the rack structures 42 is secured a cable 51 which passes over the sheave and is connected to a counterweight 52 inside of each of the tubes, which is used to relieve the lift-ing mechanism of vsonrie of the weight when it is required to raise the loop-extending'rolls.

' -'li`he manner of raising the loopfextending rolls, Anornially located near the bottoni o1 the tank, will be clearly apparent from the foregoing description when considered` in connection with the drawings. l

Should the sheet 26 become brolren from any cause and it becoines necessary to pass an unbroken sheet thru the machine it is l only required that the rolls 2'? to 31, iiiclusive, should each be raised to a-point near a horizontal plane containing the driving rolls 15 to 19, inclusive, or slightly above these rolls, which may be done by roter below the loop-extending rolls and i relatively 'stationary driving rolls, wnsre vupon the loop extending rolls, 2'? to inclusive, are then lowered into the-tank ...nd

the loops will thereby be liorined. lThe opera tion described can be quickly accomplished very little inconvenience.

'lligs 5, 6 and 7 show in detail leans for adjusting the height of either side of the lower portion of the loops and the respectivev end off the loop forming roll 129.

Located above the bracket 3'? a projection held iignly on the post 36 by a strap 61. A threaded rod 62. passes freely thru the projection 60 and'is prevented troni moving axially by the collars 63 and 64. Ifhe rod 62 is threaded at its lower end, at

65, and engages the bracket 37 atits tlireaded end.

When the bracket 37 is loosened on the posts 36 it may be raised or lowered, as required to adjust the altitude of either end othe corresponding loop-forming roll'129,

by rotation of the pivoted handle 66.

In practice only one side of the machine may be provided with these adjusting devices as any distortion of the loop may be corrected by either raising or lowering one end of the loop forming roll 129.

While I have herein shown a single embodiment of my invention for the purpose of clear disclosure, it will be manifest to persons skilled in the art, that considerable change or variation may be made in the general arrangement and configuration of the parts within the scope of the appended claims.
